Can I use my motherboard for a week without a chipset cooler?

Hey, I sold my motherboard and cpu to someone, and have another motherboard and cpu to replace it with. But as of right now I'm waiting to build it until my new video card comes.

I had a water cooled setup, But I'm adding a second video card, and don't want setup my water cooling with the new i7 cpu until my video card arrives. Dont have enough tubing to re-do it. It should arrive in a week.

My motherboard was sold to me with a waterblock on the chipset. In the mean time, can I still use my motherboard, even though the chipset has a empty water block that isnt being cooled right now?

Everything else will be fan cooled in the mean time.

Temporary Setup:
Watercooled i7, X1900, fan cooled hd4870.

New Setup once Video Card Arrives:
Water cooled i7, HD4870, HD4870, Chipset on motherboard, Hard drive (maybe)
